The core functionality of ONYX revolves around its BlueSky post scheduler, allowing users to plan and publish posts automatically at optimal times. This includes a drag-and-drop content calendar for easy organization and a "best-time-to-post" tool that uses data to suggest ideal publishing windows, moving beyond guesswork.
A standout feature is the AI Voice writing assistant. This tool analyzes a user's past BlueSky posts to learn their unique writing style, rhythm, and word choices. It then generates new draft posts that sound authentically like the user, helping to maintain a consistent brand voice without sounding robotic. Users can input a topic and receive multiple draft options to choose from, which they can then edit and schedule.
ONYX also addresses common challenges with BlueSky's character limits through its thread composer. It can automatically split long text into coherent threads, ensuring no mid-word cuts and a clean presentation. Other creator tools include a character counter, hashtag generator, and content calendar templates.
For analytics, ONYX provides insights into engagement trends, identifying best-performing posts, and offering data on follower growth, likes, reposts, and reply counts. It also includes an insights suite that helps users understand who doesn't follow back and discover effective hashtag combinations.
The platform offers a Free plan, which includes 5 scheduled posts per month, one BlueSky account, image uploads, and access to the full scheduling calendar. For more extensive use, the Pro plan at $7/month provides unlimited posts, AI Voice, the AI thread generator, and the full analytics suite. The Studio plan, priced at $19/month, caters to power creators and agencies by adding support for multiple BlueSky accounts, evergreen auto-recycling, bulk CSV scheduling, and priority access to advanced AI models.
ONYX emphasizes security by using BlueSky app passwords, which are encrypted with AES-256-GCM and can be revoked at any time. The tool is built by a single developer, focusing on a lean infrastructure to keep pricing fair and avoid feature bloat, ensuring a sharp and reliable experience for its dedicated BlueSky user base.
